How do I put the plugin into sketchup after I dl it?

I can't seem to put a line onto a cylinder using the drape tool.

How can I draw on a curved surface? Thank you.

Just starting to mess around with sketchup, can someone give me an idea/link on something to do? Thanks.

up..

Really don't have anything.

Heh, something just a tad easier maybe?

Haha, whoa now, lets start a little easier

trying to test my sketch up skills, if you need anything done at all in sketchup let me know, or want to give me a challenge, just trying to see what I can do. Thanks.
